Glasses perched on her nose, the silver-haired librarian slow-grinds her younger patient on the couch, her thick thighs squeezing his hips while she rides with deliberate control. Her gray sweater rides up just enough to reveal the soft curve of her belly as she leans back, taking him deep with each slow roll of her hips. Glasses slip lower as her breath hitches, fingers digging into his shoulders while she sets a pace that’s all about teasing, not rushing. Stockings stay snug, the only sound the quiet squeak of the couch springs under her weight. Younger guy grips her waist but lets her set the rhythm, his cock buried where she wants it most.
